Sorry to be a wet blanket, WVHighlander, but there are some drawbacks to your design.
Chas suggested the postage stamp test, and it is a good one.
What you will find is that while the two crosses moline can still be made out, and perhaps the bird in chief, the bear in base is somewhat lost.
You could try using just the bear’s head instead of the whole bear.
And by narrowing the fess (call it a bar, or a barrulet, even) you will gain space to display your other charges.

I do like Harold Cannon’s design.
Regards,
Mike
